2.6  Onboard Headers and Connectors
Onboard headers and connectors are NOT jumpers. Do NOT 
place jumper caps over these headers and connectors. Plac-
ing jumper caps over the headers and connectors will cause 
permanent damage to the motherboard!
USB 2.0 Headers
(8-pin USB_4_5)
(see p.10, No. 23)
(8-pin USB_6_7)
(see p.10, No. 24)
Besides four default USB 2.0 
ports on the I/O panel, there 
are two USB 2.0 headers on 
this motherboard. Each USB 
2.0 header can support two 
USB 2.0 ports.
This is an interface for print 
port cable that allows conve-
nient connection of printer 
devices.
Print Port Header
(25-pin LPT1)
(see p.10, No. 14)
Chassis Fan Connector
(3-pin CHA_FAN1)
(see p.10, No. 6)
Please connect a fan cable 
to the fan connector and 
match the black wire to the 
ground pin.
CPU Fan Connector
(4-pin CPU_FAN1)
(see p.10, No. 5)
Though this motherboard 
provides a 4-Pin CPU fan 
(Quiet Fan) connector, 3-Pin 
CPU fans can still work suc-
cessfully even without fan 
speed control. If you plan to 
connect a 3-Pin CPU fan, 
please connect it to Pin 1-3.
